Traffic Shaping with 2 pfsense firewalls into DMZ

[lolemel]

Hi.
We are implementing a new DMZ network.
Currently, we have only 1 pfsense server, so we don´t have problems configuring QOS.

This is our new infraestructre details:

external FW –--> DMZ ----> internal FW ----> LAN

So, our question is how to implement QOS with traffic shaper here.
We need to create same queues into both firewalls?  only in internal or external one?
Please, We need all the information about this

Thanks
